Reactivity of Candida rugosa lipase in cetyltrimethylanimonium bromide microemulsion-gelatin complex organogels

Esterification activity of Candida rugosa lipase in cetyltrimethylammonium bromide (CTAB) microemulsion-based organogels (MBGs) containing gelatin as natural resource polymer was investigated. The lipase activity reached maximum at a water content of 48-50% (v/v) and at a CTAB concentration of 60 mM. During batch repeated reactions, the lipase activity gradually decreased and the MBGs were swollen in appearance. (c) 2007 Elsevier B.V. All rights reserved.
